1. Always use a BMS – monitor voltage, current, and temperature during charge/discharge.
2. Avoid heat & fire – keep away from heat sources, open flames, and corrosive chemicals.
3. No short circuit – never reverse polarity or short-circuit terminals with metal objects.
4. Do not mix cells – use cells of same model, capacity, and batch for pack assembly.
5. No mechanical abuse – do not crush, puncture, drop, or disassemble the cell.
6. Proper storage – store at 30%~50% SOC in cool, dry place away from direct sunlight.
7. Protective gear – wear insulated gloves when handling cells.
8. If damaged – immediately stop use if cell leaks, smokes, or deforms; contact supplier.
🔋 Applications: The CATL 271Ah LiFePO₄ cell is ideal for electric vehicles (EVs), hybrid electric vehicles (HEVs), large-scale energy storage systems (ESS), solar battery banks, marine propulsion, UPS backup, and industrial equipment.
